Scorpions are members of the class Arachnida and are closely related to spiders. There are approximately 2,000 species of scorpions but only about 30-40 types of scorpions have venom strong enough to kill a person.
Scorpions will typically eat insects. When food is scarce, the scorpion has an amazing ability to slow down it’s metabolism. This enables some species of scorpions to use little oxygen and live on as little as a single insect per year. Even with lowered metabolism, a scorpion has the ability to spring quickly to the hunt when the opportunity presents itself.
The scorpion’s survival skills allow them to live in some of the toughest environments, but there is an exception. Scorpions have a difficult time living without soil. They are burrowing animals, so if there is not loose soil available, then scorpions may not be able to survive.
